1 Rationalizing the Denominator Presented by Kathryn Maloney Binomial Denominators

2 Rationalizing the Denominator (1) Multiply both the numerator and denominator by the conjugate of the denominator. (2) Simplify the result.

3 Cool Math Term Conjugate Surd A surd is a root that can’t be simplified further.

4 Product of Two Conjugates Product of the sum and difference of two terms. FOIL!

5 Perform the indicate division. (Rationalize the denominator) What is the conjugate of the denominator?

6 Perform the indicate division. (Rationalize the denominator) Press pause, find the solution, and play to check your answer!
